In this blog post for the Innosight Institute (now the Clayton Christensen Institute for Disruptive Innovation), Bryan Hassel and Emily Ayscue Hassel argue that “schools – and nations – that excel in the digital age will be those that use digital tools both to make teaching more manageable for the average teacher, and to give massively more students access to excellent teachers.” While digital learning can help solid teachers become more effective, one of its greatest promises is to enable top teachers – those whose students already achieve well over a year’s worth of growth – to educate more students by freeing up their time, allowing them to teach students who are not physically present, and capturing their teaching prowess by recording videos or helping develop smart learning software.
